Alexey Samsonov 1cb684381a [Sanitizer] Add generic ThreadRegistry class for sanitizer runtimes. This class holds basic thread bookkeeping logic and allows specific sanitizer runtimes to create thread contexts and mark threads as created/running/joined etc. The class is based on the way we currently store thread contexts in TSan.

Kostya Serebryany f0b8f989e9 add Linux syscall wrappers and ThreadLister to sanitizer_common
ThreadLister is a Linux-specific class for obtaining the thread IDs of a process from procfs (/proc/<pid>/task/). It will be used by leak checking code.
Also add several syscall wrappers which will be required by the same code that uses ThreadLister, but are not used in ThreadLister itself.

Kostya Serebryany 9f298da9bd [asan] instrument memory accesses with unusual sizes
This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or
packed structures.
Instrumentation is done with two 1-byte checks
(first and last bytes) and if the error is found
__asan_report_load_n(addr, real_size) or
__asan_report_store_n(addr, real_size)
is called.

asan-rt part

Evgeniy Stepanov 87c43537df [sanitizer] Improve scanf interceptor
This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.

I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.
